First off, the all-new Activity view has been added to the Mac client. Like in the iOS version, you’ll find all of the recent favorites, retweets, and other interactions you’ve received in this tab. Quoted tweets also show in the mentions tab to help improve conversation flow.

Support for in-app viewing of videos from Twitter, Instagram, and Vine has been added, and Twitter’s native video hosting service has been added as an upload option. Images now appear in direct message threads, and the image viewer supports pinch-to-zoom. Another popular gesture, swiping back in profiles views, is also supported.

A few extra functional changes have been made for added convenience. Searching for other users when composing a tweet will now show better, more accurate results. The tweet detail view allows you to select text, and the “retweets” button on that view will now pull up a list of everyone who retweeted a specific post. Finally, a “scroll to last read” option in the View menu will let you quickly jump back to your previous position if you’ve scrolled away from it.

As usual, bugs have been squashed and performance improvements have been made. You can download Tweetbot 2.1 as a free update from the Mac App Store. New buyers will need to pay $12.99 the new, lower price of $9.99.
